Application filed April 13, 1921.

T 0 all whom it may concern:

Be it known that l, SAMUEL ll. Sonnntt, a citizen of the United States,residing at Ashland, in the county of Clay and State of Alabama. haveinvented a new and useful Shaker Grate, of which the following is aspecification.

This invention aims to provide novel means whereby a shaking operationmay be carried out in a fire-place grate.

It is within the province of the disclosure to improve generally and toenhance the utility of devices of that type to which the inventionappertains.

lVith the above and other objects in view, which will appear as thedescription proceeds, the invention resides in the combination andarrangement of parts and in the details of construction hereinafterdescribed and claimed, it being understood that, within the scope ofwhat is claimed, changes in the precise embodiment of the inventionshown can be made without departing from the spirit of the invention.

In the drawing Figure 1 shows in front elevation. a d vice constructedin accordance with the in vention; Figure 2 is a top plan; Figure 3 isan end elevation; Figure at is a rear elevation wherein remote parts areomitted; Figure 5 is a bottom plan; Figure 6 is a section on the line6-6 of Figure 1.

In carrying out the invention, there is provided a frame including afront post 1 and a front post 2, the post 2 extending downwardly agreater distance than does the post 1. The posts 1 and 2 are suppliedwith rearwardly extended hooks 3, whereby the frame may be held in afire-place. The posts 1 and 2 are connected by front bars 1 and 5, thelower of the said bars being denoted by the numeral 5. it back' piece 6is provided. Right-angled grate bars 7 connect the front bar 5 with theback piece 6. For a purpose to be explained hereinafter, the back piece6 is cut away on its forward surface to form recesses 8. At one end, theback piece 6 is supplied with adepending fiXed bearing 9. On the otherenrl of the back piece 6 is mounted a removable bearing 10, secured tothe back piece as indicated at 11.

The reduced ends 12 of a rock shaft 14- are mounted in the bearing 10and 9. The rock shaft 14 carries forwardly extended fingers 15 locatedbetween the horizontal Specification of Letters latent.

portions of the grate bars 7. At their rear ends, the fingers 15 are cutaway as shown at 16, to clear the lower portion of the back piece 6, theupper rear portions 17 of the fingers 15 being adapted to be received inthe recesses 8 of the back piece 6. The construction last abovedescribed permits the fingers 15 to have an increased amount of up anddown vertical swinging movement. At one end, the rock shaft 14 carries adepend ing crank arm 18. A forwardly extended link 19 is pivoted at 20to the crank arm and is mounted for reciprocation in an opening 21formed in the post 2 near to the lower end thereof. The post 2 has aforwardly er:- tended car 22, whereon the lower end of a lever 23 isfulcrumed as shown at 24. The forward end of the link 19 is pivoted at25 to the lever 23.

In practical operation, the fingers 15 on the rock shaft 1% are disposedhorizontally, between the horizontal portions of the grate bars 7 Owingto this construction, the spaces between the horizontal portions of therate bars 7 are closed to some extent and, consequently, a relativelyfine coal or other fuel may be used. The fingers 15 tend to prevent fineparticles of fuel from falling between the grate bars 7. It is possible,however, to impart rocking movement to the shaft 14, by way of the link19 and the lever 23. Under such circumstances, the fingers 15 on therock shaft 14 will swing upwardly and downwardly between the grate bars7 and permit a shalt-- ing of the device. The construction is such thata clean, bright fire may be maintained at all times, without poker workand, it is to be noted, the fine particles of fuel will be held back andburned, only the finely divided portions of the ashes passing betweenthe fingers 15 and the horizontal portions of the grate bars 7.

Having thus described the invention, what is claimed is 1. In a deviceof the class described, a frame embodying front posts, a front barconnecting the posts, a back piece, and grate bars connecting the frontbar with the back piece; a shaft mounted to rock on the back piece;fingers carried by the shaft and loeated between the grate bars; a levern1ount ed to swing on one post; and a link forming a connection betweenthe lever and the shaft, the said post having an opening for thereception of the link.

2. In a device of the class described, a frame including grate bars; ashaft mounted to rock on the rear portion of the fran'ie and providedwith fingers extended between the grate bars; a crank arm on the shaft;an upwardly extended lever disposed in front of the frame and fulcrumedat its lower end on the frame; and a link forming an operativeconnection between the intermediate portion of the lever and the crankarm.

3. In a device of the class described, a frame comprising grate bars andaback piece connecting the grate bars, the back piece being provided inits forward surface with a recess; a shaft mounted to rock on the backpiece; fingers. carried by the shaft and cooperating with the backpiece, the fingers being cut away to clear the back piece and beingextended into the recess; and means for rocking the shaft.

In testimony that I claim the foregoing as my own, I have heretoaflixedmy signature in the presence of two witnesses.
